Miley Cyrus is gushing about her beau, Liam Hemsworth, and her next album in the upcoming issue of Cosmopolitan.

The former "Hannah Montana" star said she's most satisfied with her relationship with Hemsworth, whom she met on the set of their 2009 film "The Last Song." Hemsworth proposed in May 2012.

"I'll literally look at him and be like 'You are hot, dear God!'" she told the mag. "The other day, I turned on the pool heater and it was steaming, and he walked outside and took off his clothes and jumped in the pool. I was like, 'I'm gonna faint -- the hottest guy of my life is in a steaming pool. This looks like a Playgirl shoot.'

"So I took a photo and made it the background on my phone. My best friend grabbed my phone and was like, 'Who's that? He is so hot!' That's my hubby!"

That last sentence fueled existing rumors that Cyrus, 20, and "The Hunger Games" actor already got hitched over the holidays. Though she may be hiding her marital status, she isn't hiding her obsession with her Aussie beau, which she says is the one thing in her life she's currently most satisfied with.

"Number one is my relationship with Liam. That's what I feel the most confident in because you never know; there's so much hype behind my new record, but it could come out and, worst-case scenario, everyone ... hates it," she said.

Cyrus is gearing up to release her next album -- another racy break with her once-shining Disney brand, judging from that semi-bare frontal photo she took for Cosmo cover.

"[The album is] the second thing that I'm most content with. I've never gotten to make a record like this because Disney's always been on my back saying, 'You've got to promote the TV show in two months, so make sure your record's done ... and when you promote your record, can you promote the show, the movie, and the 'Hannah Montana' record?' " she said.

"I was basically carrying two people's careers and trying to make mine the priority. Now, it's almost like being a new artist and trying to make a first impression. I think the best thing I could have done was take those two years off to really live, because now people don't think of me as who I was on the TV show."

She adds: "Some of the worst things that have happened in my career, like things getting leaked, have actually been what's best for me, because people knew when I was on that show that I was really growing up. I never faked anything. I never played the Disney game of smiling and being a princess and then suddenly having a hard time, saying, 'That isn't who I really am.' "

Salvia, sexy birthday cakes, stripper poles and strip-teases come to mind .... The singer-actress is currently vacationing (or honeymooning, who knows!) in Costa Rica with Hemsworth and doing some bikini-clad yoga on the beach. See the video above.

The album features a song she co-wrote with Mary J. Blige and a guest spot from Tyler the Creator. She's also been pulling inspiration from Frank Ocean and her friend Katy Perry and celebrates her competition: Rihanna, Nicky Minaj and Ke$ha.
